Abstract
Cellulose nanocrystals with cellulose II polymorph (CNC-II) were obtained from primary sludge fiber (PSF) in a pulp and paper mill by sulfuric acid hydrolysis after purification to remove inorganic materials and lignin. The CNC-IIs obtained were applied as reinforcing fillers for polyvinyl alcohol (PVA). Characterization of CNC-IIs was performed using FTIR spectroscopy and X-ray diffraction. The morphology, conductivity, and tensile properties of CNC-IIs-reinforced PVA nanocomposites were also investigated. Purification treatment effectively reduced non-cellulosic material in the sludge, increasing the cellulose content from 39.87 to 76.34%. The conductivity and tensile properties of the PVA/CNC-II nanocomposite was better than those of neat PVA and PVA/PSF composite.
